Assessing the Impact of Imaging Parameters on MRI Measurement of Kidney T₂.

ABSTRACT:

Background

T₂-mapping has promise to evaluate kidney pathophysiology. Prior studies show a large variance in kidney T₂, likely due to the differing acquisition sequences.

Purpose

To compare four T₂-mapping sequences to investigate kidney T₂.

Study type

Phantom and prospective in vivo assessments.

Participants

ISMRM/NIST and QASPER phantoms; 8 healthy volunteers (4 female, 30 ± 8 years).

Field strength/sequence

3 T, spin echo-echo planar imaging (SE-EPI), multi-echo-spin echo (ME-SE), Gradient and Spin Echo (GraSE) vendor-provided sequences, and custom T₂-prepared EPI, Dual-echo B₀-mapping and DREAM B₁-mapping.

Assessment

T₂-mapping accuracy in the ISMRM/NIST ph
